Question

Area receiving average annual rainfall > 1150 mm are categorized as

• A. Dry farming
• B. Dry land farming
• C. Dry land agriculture
• D. Rainfed farming

Hint:

Dry farming: $< 750\,\text{mm}$; Dryland farming: $750\text{--}1150\,\text{mm}$; Rainfed farming: $> 1150\,\text{mm}$.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Dryland and rainfed agricultural systems are classified based on the mean annual precipitation received.

Step 2: Detailed Explanation:
The standard classification based on annual rainfall is:
1. Dry Farming: Annual rainfall $< 750\,\text{mm}$ (frequent crop failure, moisture conservation focused).
2. Dryland Farming: Annual rainfall between $750\,\text{mm}$ and $1150\,\text{mm}$ (semi-arid regions, drainage and conservation).
3. Rainfed Farming: Annual rainfall $> 1150\,\text{mm}$ (humid and sub-humid regions, focus on drainage and runoff management).

Step 3: Final Answer:
Thus, areas receiving annual rainfall $> 1150\,\text{mm}$ are categorized as rainfed farming.
